Donald Trump announces plan to abolish daylight saving time due to its perceived costs

According to the provided articles, Donald Trump has announced that the Republican Party will attempt to abolish daylight saving time. Trump claims that this practice is "inconvenient" and "very costly" to the nation. The practice of moving clocks forward in spring and backward in autumn has been adopted by a third of the world's countries, and some in the US have long advocated for its elimination. It is worth noting that Trump's statement is not the first time the issue has been brought up, as some lawmakers have previously proposed abolishing the time change altogether.
